Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.

2. Lift the Vehicle

Use a jack to lift the front of the vehicle.
Secure the vehicle with jack stands to prevent any accidents.

3. Remove the Wheel

Use a lug wrench to remove the lug nuts from the wheel and take the wheel off.

4. Inspect and Replace the Ball Joint

Inspection: Check the ball joint for any signs of wear, including cracks or torn boots.
Removal:
- Disconnect any components that may obstruct access to the ball joint, such as brake lines or CV axle.
- Use a socket set to remove the nut securing the ball joint to the control arm.
- Use a ball joint separator or pickle fork to detach the ball joint from the steering knuckle.
Installation:
- Install the new ball joint into the steering knuckle and secure it with the appropriate nut.
- Reattach any components that were removed during disassembly.
- Torque the ball joint nut to the manufacturer’s specifications (usually around 35-50 ft-lbs, but check specifications for accuracy).

5. Reassemble

Place the wheel back onto the hub and hand-tighten the lug nuts.
Lower the vehicle and then torque the lug nuts to the manufacturer’s specifications (usually around 80-100 ft-lbs).
